Prior to this fix the `swipe` modifier could not be disabled and we were not using the `this.dimissable` property to apply/not apply it.
This commit adds a new `enabled` param to the `swipe` modifier, which is used in modals with the value of `this.dismissable`.
Note this commit also adds tests for this modifier.
Why this change?
Before this change, the validation error message shown to the user when
saving a theme objects setting is very cryptic. This commit changes the
validation error messages to be displayed on top of the editor instead.
Note that I don't think this way of displaying is the ideal state we
want to get to but given the time we have this will do for now.
Why this change?
In the categories, groups and tags selectors, we were showing a
validation error message when a property that is not required but
has a min validation is empty. In this case, we should not be displaying
the min validation error message because the property is allowed to be
empty.
Why this change?
When adding a new object, we want to switch to the input fields of the
new object instead of just appending the new object to the list of
objects as we believe this is a better UX flow.
Why this change?
The field components to select categories, groups and tags had quite a
bit of logic duplicated between them. This commit refactors the logic
to remove most of the duplication so that we can introduce changes
without having to make the changes in multiple places.
* DEV: Various bulk-select dropdown tweaks
- Setting is no longer hidden
- descriptions have been moved to the modal
- Removed ... from one of the dropdown titles
... rather than just the category id.
In order for the user to have selected a category, the category must
have been loaded and it's useful for the category chooser to provide
this fetched category so that it doesn't need to be refetched.
In the future, it would be better to store the categories that the
chooser knows about in local component state, so that the category
doesn't need to be fetched from the id map, but this, at least, puts the
API in place.
Why this change?
This is a follow-up to 86b2e3a.
Basically, we want to allow people to select more than 1 group as well.
What does this change do?
1. Change `type: group` to `type: groups` and support `min` and `max`
validations for `type: groups`.
2. Fix the `<SchemaThemeSetting::Types::Groups>` component to support the
`min` and `max` validations and switch it to use the `<GroupChooser>` component
instead of the `<ComboBoxComponent>` component which previously only supported
selecting a single group.
Why this change?
Prior to this change, the `SchemaThemeSetting::Editor#tree` was creating a
new `Tree` instance which holds instances of `Node`. Both classes
consisted of tracked properties. The problem with this approach is that
when any tracked properties is updated, Ember will revaluate
`SchemaThemeSetting::Editor#tree` and because that method always return
a new instance of `Tree`, it causes the whole navigation tree to
rerender just because on tracked property changed.
This rerendering of the whole navigation tree every time made it hard to
implement simple features like hiding a section in
9baa820d53. Instead of being able to just
declare a tracked property to hide/show a section, we end up with a more
complicated solution.
This commit rewrites `SchemaThemeSetting::Editor` to depend on Ember
components to form the tree structure instead. As needed, each component
in the tree structure can declare its own tracked property as necessary.
Why this change?
In cdba864598, we added support for adding
a description which will be displayed under the input of each property
on the client side.
Currently this convention in the locale file is followed:
```
en:
theme_metadata:
settings:
objects_setting:
description: <description> for the setting
schema:
properties:
name: <description for the name property>
links:
name: <description for the name property in link>
url: <description for the url property in link>
```
Since we now want to allow the label to be translated as well, we will
be changing the convention to the following:
```
en:
theme_metadata:
settings:
objects_setting:
description: <description> for the setting
schema:
properties:
name:
label: <label for the name property>
description: <description for the name property>
links:
name:
label: <label for the name property>
description: <description for the name property in link>
url:
label: <label for the url property>
description: <description for the url property in link>
```
If the locale file does not provide a `label` key under the property's
name, the client side will just display the property's name as the
label for the input field.
Applying `overflow: hidden` was not playing well with sticky elements (like the header for example). It appears that we don't really need this to achieve our goal so Im removing this part of body scroll lock for now.
Descriptions for the `category-list`, `file-size-restriction` and `file-types-list` site/theme settings aren't rendered due to a bug that was introduced when those components were migrated to Glimmer components. This commit fixes the bug which is that arguments passed to .gjs components should be accessed as `@argument` and not `this.arugment` inside the `<template>` tag.
This will prevent any scrolling issues with sk when on mobile, especially on iOS and in modals.
Prior to this fix, scrolling could sometimes stop working in dropdowns.
This commit is making the following changes:
- replaces `mobile-keyboard` initializer and `chat-vh` with a new template-less component: `d-vh`
- ensures body scroll lock is released when page/tab focus changes
- correctly locks body on chat channels and chat threads when composer is focused
- removes `bodyScrollFix` as we now use body scroll lock
- `onViewportResize` has been debounced to ensure it's not a bad performance vector
- adds a reverse option do body scroll lock, this is made to support reversed scroll areas (like chat channels and threads)

Why this change?
This is a follow-up to 86b2e3aa3e.
Basically, we want to allow people to select more than 1 category as well.
What does this change do?
1. Change `type: category` to `type: categories` and support `min` and `max`
validations for `type: categories`.
2. Fix the `<SchemaThemeSetting::Types::Categories>` component to support the
`min` and `max` validations and switch it to use the `<CategorySelector>` component
instead of the `<CategoryChooser>` component which only supports selecting one category.
Prior to this fix the options were not passed down when the user had no default calendar.
No test as it's mostly an interaction between discourse-calendar and core which is hard to test.
This lib will allow us to wait for a keyboard state change. Not waiting for the keyboard to be closed could cause issues when showing a modal at the same time on iOS for example.
Example usage:
- blurSomeInput()
- await waitForClosedKeyboard(this)
- showSomeModal()
Note that this actual behavior has been baked in modals when we call show so you don't have to call the lib yourself.
Why this change?
Previously, we were preloading the necessary metadata for
`adminCustomizeThemes.show.schema` route in the
`adminCustomizeThemes.show` route. This is wasteful because we're
loading data upfront when the objects setting editor may not be used.
This change also lays the ground work for a future commit where we need
to be shipping down additional metadata which may further add to the
payload.
Why this change?
When a property of `type: tags` is required, we should be displaying the
"at least 1 tag is required" validation error message when there are no
tags selected in the `TagChooser` compoment. However, we were passing
`this.min` as the `count` attribute when generating the translation
string which is incorrect as `this.min` is not always set.
This commit mainly improves three things:
- slide up/down animation of the modals on mobile, also allowing swipe down to close the modal
- body scroll locked modals, it means that only the body of the modal can scroll
- a new `<:headerPrimaryAction>` block for `d-modal` which when present will move the cancel button to the left of the modal title, and this primary action to the right of the title
- Converts all header buttons to use `<DButton`
- Updates `<DButton` to render `<a href=` tags when `@href` is passed (previously it was rendering a `<button`, and then using JS to route when clicked)
Why this change?
While working on the tag selector for the theme object editor, I
realised that there is an extremely high possibility that users might want to select
more than one tag. By supporting the ability to select more than one
tag, it also means that we get support for a single tag for free as
well.
What does this change do?
1. Change `type: tag` to `type: tags` and support `min` and `max`
validations for `type: tags`.
2. Fix the `<SchemaThemeSetting::Types::Tags>` component to support the
`min` and `max` validations
Why this change?
Prior to this change, the category selector was not clearable and did
not allow a none value. This is incorrect as the category selector
should be clearable and should allow a none value when the property is
not required.
We are still making improvements to the admin sidebar and
various parts of the admin section. For now, to make the
transition easier, we are moving this link to the top of the
sidebar so it's clear that admins can still get to all settings
if they need to.
Why this change?
Prior to this change, the group selector was using the `<GroupChooser>`
component which is a `<MultiSelectComponent>` and is not ideal in our
situation when we only allow a single group to be selected.
The other problem is that we are doing an async load of the groups when
it is already loaded and available in the `Site` service.
Previously, we had an instant redirect back to the homepage, and clicking avatars would do nothing. This made things feel 'broken' for anon when 'hide_user_profiles_from_public' was enabled.
This commit does a few things to resolve this:
1. Improve our 'exception' system for routes so that developers can deliberately trigger it without an ajax error
2. Improve 'exception' system so that the browser URL bar is updated correctly, and the 'back' button works as expected
3. Replace the redirect-to-home with an 'access denied' error page, with specific copy for 'You must log in to view user profiles'
4. Update user-card logic to display this new page instead of doing nothing on click
There is no need to use an initializer and manually update the DOM when
a Glimmer component can do it and ensure that the DOM is updated as more
categories are being loaded (for example, when lazy loaded categories
are enabled).
Why this change?
This is a continuation of a30d73f255
In our schema, we support the `min` and `max` validation
rules like so:
```
some_objects_setting
type: objects
schema:
name: some_object
properties:
id:
type: float
validations:
min: 5
max: 10
```
While the validations used to validate the objects on the server side,
we should also add client side validation for better UX.
What does this change do?
Since the integer and float input fields share very very similar logic
in the component. This commit pulls the common logic into
`admin/components/schema-theme-setting/number-field.gjs` which
`admin/components/schema-theme-setting/types/integer.gjs` and `admin/components/schema-theme-setting/types/float.gjs`
will inherit from.

This commit changes the API for registering the plugin config
page nav configuration from a server-side to a JS one;
there is no need for it to be server-side.
It also makes some changes to allow for 2 different ways of displaying
navigation for plugin pages, depending on complexity:
* TOP - This is the best mode for simple plugins without a lot of different
custom configuration pages, and it reuses the grey horizontal nav bar
already used for admins.
* SIDEBAR - This is better for more complex plugins; likely this won't
be used in the near future, but it's readily available if needed
There is a new AdminPluginConfigNavManager service too to manage which
plugin the admin is actively viewing, otherwise we would have trouble
hiding the main plugin nav for admins when viewing a single plugin.
Why this change?
If an object doesn't have any child objects for a particular property
and we try to add one through the editor, an error will be raised.
```
Cannot read properties of undefined (reading 'push')
at SchemaThemeSettingEditor.addItem (editor.js:190:1)
```
All our link validation, and conversion from url -> route/model/query is expensive and prone to bugs. Instead, if people enter a link, we can just use it as-is.
Originally all this extra logic was added to handle unusual situations like `/safe-mode`, `/my/...`, etc. However, all of these are now handled correctly by our Ember router, so there is no need for it.
Now, we just pass the user-supplied `href` directly to the SectionLink component, and let Ember handle routing to it when clicked.
The only functional change here is that we no longer validate internal links by parsing them with the Ember router. But I'd argue this is fine, because the previous logic would cause both false positives (e.g. `/t/123` would be valid, even if topic 123 doesn't exist), and false negatives (for routes which are server-side only, like the new AI share pages).
Currently, a new sidebar link for what's new and reports is going to the main dashboard page and activates the proper tab.
It might be problematic, especially, when the instance has a lot of problems. In that case, it would be difficult for admin to find reports or what’s new which is rendered at the bottom of the page.
Therefore separate pages for reports and what's new were created.
Reports were moved to a component that is shared between a separate page and the dashboard.
This commit fixes an issue where the following happens:
1. You open /admin as a member of the admin_sidebar_enabled_groups
1. You then click the chat icon in the header when you prefer to have
drawer open, or if you just minimise chat into drawer after it opens
fullscreen
1. You lose the admin sidebar panel, and are reset instead to the main
panel
Also included is a bit of refactoring to make it so the forcing of
admin sidebar state is in one place.
Previously we were only running the `condition` function once, and then overwriting it with a static boolean value. Future changes to composer attributes would not affect button visibility.
This commit fixes the issue and adds an acceptance test for the behavior.
Prior to this fix, if you were following this series of events:
- type something in a select-kit filter with async search
- query starts
- type something again
- first query finished with no results
- second query starts
- 💥 we would show a no content found for a split second
- second query finishes
- we display a list of results
This commit now ensures we will properly attempt to refresh the toolbar position after a scroll and consider it as a selection change.
Tangential to this fix we improved the positioning on mobile to better account for the native menu position and avoid a situation where the toolbar is always behind the native menu and can't be used.
Adds `@tracked` to the relevant property on the User model so that it is autotracked correctly via the function call `glimmer-header/user-dropdown/notifications#isInDoNotDisturb` -> `models/user#isInDoNotDisturb`.
Why this change?
This is a first pass at styling the editor for creating/editing/updating
an objects typed theme setting. Only the desktop view is being
considered at the current moment.
The objects typed theme setting is still behind a feature flag at this moment so there is no need for us to get the styling perfect. The purpose of this PR is to get us to a state which we can quickly iterate with a designer on.
This commit makes it so the site settings filter controls and
the list of settings input editors themselves can be used elsewhere
in the admin UI outside of /admin/site_settings
This allows us to provide more targeted groups of settings in different
UI areas where it makes sense to provide them, such as on plugin pages.
You could open a single page for a plugin where you can see information
about that plugin, change settings, and configure it with custom UIs
in the one place.
In future we will do this in "config areas" for other parts of the
admin UI.
This commit moves the generation of category background CSS from the
server side to the client side. This simplifies the server side code
because it does not need to check which categories are visible to the
current user.
Why this change?
When editing a objects typed theme setting, the input fields which are
rendered should include a description so that the user knows the purpose
of the field which they are changing.
What does this change do?
This change adds support for adding description to each property in the
schema for an object by following a given convention in the locale file.
For a schema like this:
```
objects_setting:
type: objects
schema:
name: section
properties:
name:
type: string
required: true
links:
type: objects
schema:
name: link
properties:
name:
type: string
required: true
validations:
max_length: 20
url:
type: string
```
Description for each property in the object can be added like so:
```
en:
theme_metadata:
settings:
objects_setting:
description: <description> for the setting
schema:
properties:
name: <description for the name property>
links:
name: <description for the name property in link>
url: <description for the url property in link>
```
If the a description is not present, the input field will simply not
have an description.
Also note that a description for a theme setting can now be added like
so:
```
en:
theme_metadata:
settings:
some_other_setting: <This will be used as the description>
objects_setting:
description: <This will also be used as the description>
```
> [code]
> line1
> line2
> [/code]
would render as
| line1
| > line2
instead of the correct
| line1
| line2
That was due to the `bbcode-block` code using a `slice` to get the content of a block and not taking into account it being nested in a quote block for example.
The fix was to get the content using the `getLines` utils method.
Context: https://meta.discourse.org/t/markdown-bbcode-code-quote-bug/299047
This reverts the "fix" made in 44f6b24e34 since it wasn't the correct fix and the emoji picker wasn't showing in chat 🤦♂️
The proper fix is to `stopPropagation()` on the `click` event since the click handler has been made `async`. `preventDefault()` isn't enough.
Should open the emoji picker. But it wasn't 😅
The `handleOutsideClick` event was listening too early and would catch the click on the "more..." option in the autocomplete as a click outside the emoji picker and would immediately close it 🤦
The fix was to defer registering to this event.
With the new admin sidebar restructure, we have a link to "Installed plugins". We would like to ensure that when the admin is searching for a plugin name like "akismet" or "automation" this link will be visible. Also when entering the plugins page, related plugins should be highlighted.
Why this change?
Prior to this change, there is no description being displayed for
objects typed theme setting because we were rendering a button instead
of the components for the various setting types which will render the
setting's description.
What does this change do?
1. Introduce `SiteSettings::Description` compoment to centralise the HTML
being rendered across all settings component.
2. Renders the `SiteSettings::Description` component after the edit
button in `site_setting.hbs`.
This commit adds new plugin show routes (`/admin/plugins/:plugin_id`) as we move
towards every plugin having a consistent UI/landing page.
As part of this, we are introducing a consistent way for plugins
to show an inner sidebar in their config page, via a new plugin
API `register_admin_config_nav_routes`
This accepts an array of links with a label/text, and an
ember route. Once this commit is merged we can start the process
of conforming other plugins to follow this pattern, as well
as supporting a single-page version of this for simpler plugins
that don't require an inner sidebar.

`apply_transformations` is an async function, and plugins/themes using it expect their transformations to be applied before the loadMore logic continues. This should resolve issues with unencrypted topics when scrolling down topic lists in discourse-encrypt.
**TL;DR:** Refactor autocomplete to use async markdown parsing for code block detection.
Previously, the `inCodeBlock` function in `discourse/app/lib/utilities.js` used regular expressions to determine if a given position in the text was inside a code block. This approach had some limitations and could lead to incorrect behavior in certain edge cases.
This commit refactors `inCodeBlock` to use a more robust algorithm that leverages Discourse's markdown parsing library.
The new approach works as follows:
1. Check if the text contains any code block markers using a regular expression.
If not, return `false` since the cursor can't be in a code block.
1. If potential code blocks exist, find a unique marker character that doesn't appear in the text.
1. Insert the unique marker character into the text at the cursor position.
1. Parse the modified text using Discourse's markdown parser, which converts the markdown into a tree of tokens.
1. Traverse the token tree to find the token that contains the unique marker character.
1. Check if the token's type is one of the types representing code blocks ("code_inline", "code_block", or "fence").
If so, return `true`, indicating that the cursor is inside a code block.
Otherwise, return `false`.
This algorithm provides a more accurate way to determine the cursor's position in relation to code blocks, accounting for the various ways code blocks can be represented in markdown.
To accommodate this change, the autocomplete `triggerRule` option is now an async function.
The autocomplete logic in `composer-editor.js`, `d-editor.js`, and `hashtag-autocomplete.js` has been updated to handle the async nature of `inCodeBlock`.
Additionally, many of the tests have been refactored to handle async behavior. The test helpers now simulate typing and autocomplete selection in a more realistic, step-by-step manner. This should make the tests more robust and reflective of real-world usage.
This is a significant refactor that touches multiple parts of the codebase, but it should lead to more accurate and reliable autocomplete behavior, especially when dealing with code blocks in the editor.

Changing an `@tracked` value in a `willDestroyElement` hook will not immediately trigger a re-render. Instead, it seems to update on the next natural runloop iteration, which may be significantly later depending on what else is happening.
Instead, these kinds of 'data' changes should be made based on the lifecycle of the component instance (init / willDestroy). Making changes to tracked properties here does seem to cause immediate invalidation & re-render.
Why this change?
On the `/admin/customize/themes/<:id>` route, we allow admins to edit
all settings via a settings editor. Prior to this change, trying to edit
and save a typed objects theme settings will result in an error on the
server.
Why this change?
On a slow network, using the `AceEditor` component will result in a blob
of text being shown first before being swapped out with the `ace.js`
editor after it has completed loading.
There is also a problem when setting the theme for the editor which
would result in a "flash" as reported in
https://github.com/ajaxorg/ace/issues/3286. To avoid this, we need to
load the theme js file before displaying the editor.
What does this change do?
1. Adds a loading spinner and set the `div.ace` with a `.hidden` class.
2. Once all the relevant scripts and initialization is done, we will
then remove the loading spinner and remove `div.ace`.
This change creates a user setting that they can toggle if
they don't want to receive unread notifications when someone closes a
topic they have read and are watching/tracking it.
* A11Y: Update bulk selection keyboard shortcuts
Still a draft, but in current state this:
- adds `shift+b` as a keyboard shortcut to toggle bulk select
- adds `shift+d` as a keyboard shortcut to dismiss selected topic(s) (this
replaces `x r` and `x t` shortcuts)
- adds `x` as a keyboard shortcut to toggle selection (while in bulk select mode)
- fixes a bug with the `shift+a` shortcut, which was not working properly
Note that there is a breaking change here. Previously we had:
- `x r` to dismiss new topics
- `x t` to dismiss unread topics
However, this meant that we couldn't use `x` for selection, because the
itsatrap library does not allow the same character to be used both as a
single character shortcut and as the start of a sequence. The proposed
solution here is more consistent with other apps (Gmail, Github) that use
`x` to toggle selection.
Also, we never show both "Dismiss New" and "Dismiss Unread" in the same
screen, hence it makes sense to consolidate both actions under `shift+d`.
* Address review
Why this change?
Before this change, the new navigation item in the topic list will be
hidden when there are no new or unread topics for the user. We have
started to find this behaviour confusing UX wise so we decided to stop
hiding it.
Why this change?
This is a regression from introduced in
5c1147adf3 where dismissing unread topics
was changing the notification level of the topics instead of just
dismissing the unread posts.
What does this change do?
1. Bring back the previous implementation of the action
2. Fix the system test that was supposed to catch the problem but did
not.
The `home-logo-wrapper` outlet is used by chat, which means it is unavailable for use by any other themes/plugins. This commit introduces a second nested outlet called `home-logo` which can be used to replace the logo without affecting chat's header logic.
This commit improves the "+ X subcategories" option that shows sometimes
in the category selector. It used to show when there was a single match,
but now it also shows up on exact matches even though there are multiple
results.
It also makes it work when lazy_load_categories is enabled by searching
the subcategories before rendering them.
When "lazy load categories" is enabled, the CategoryDrop component will
render at most 15 categories. If there are more categories, a "Show
more" link pointing to the categories page will be displayed.
Before, the `back to forum` link was part of experimental admin navigation. It means that the link could be filtered out.
Because it is essential navigation, it should not be part of sidebar links and should be moved above the filter.
This option was introduced at some point in the past, but was removed
during the work necessary to make Discourse work with a large number of
categories.

Why this change?
The `/admin/customize/themes/:id/schema/name` route is a work in
progress but we want to be able to start navigating to it from the
`/admin/customize/themes/:id` route.
What does this change do?
1. Move `adminCustomizeThemes.schema` to a child route of
`adminCustomizeThemes.show`. This is because we need the model
from the parent route and if it isn't a child route we end up
having to load the theme model again from the server.
1. Add the `objects_schema` attribute to `ThemeSettingsSerializer`
1. Refactor `SiteSettingComponent` to be able to render a button
so that we don't have to hardcode the button rendering into the
`SiteSettings::String` component

Skipping babel for qunit is part of the default embroider blueprint. Adding these doesn't seem to have a measurable effect on build time, but it does stop this message from being printed in the build log:

Adds a site setting to include a post's content in penalty message.
When silencing/suspending a user from a post, or a reviewable with
a post, adds an option to include a post's content in the email
message by default.
When a post is created by an incoming email, we show
an envelope icon on it which then opens a modal with the
raw email contents. Previously this was staff (admin+mod)
only, but now this commit adds the `view_raw_email_allowed_groups`
site setting, so any group can be added to give users permission
to see this.
CategoryChooser component usually displays just categories, but
sometimes it can show two none values: a "no category" or Uncategorized.
This commit makes sure that these are rendered correctly.
The problem was that the "none" item was automatically inserted in the
list of options, but that should not always happen. Toggling option

With the adjustments of `btn-transparent` in https://github.com/discourse/discourse/pull/24666, there are more buttons that could use this class instead of `btn-flat`. This mostly relates to `x` close buttons, but also includes composer and chat toggles.
The primary difference between these styles is that `btn-transparent` never has a background, where `btn-flat` may have a hover or focus background.
In this PR, the admin panel remembers the previous state and restores it when the admin panel is deactivated.

However, it would be better to have a more generic solution. When the panel is changed, the previous state is saved in the sidebarState. When a user returns to the specific panel, a previously remembered state is restored.
